Interaction module in ABAQUS

Interaction module in ABAQUS

Interaction module in ABAQUS

(OP)
I am having issues with the Interaction module in ABAQUS, and the several tutorials I've found online don't seem to address this issue. Basically I'm modeling the compression of a cylinder, and for some reason the post-compression results don't look like they should be. I attached the images as below.

I expected the cylinder to be compressed such that majority of the cylinder surface post-compression is contacting the top and bottom blocks. However, as you can see from the results, Only the initial portion is connected. I also attached the Assembly picture and a zoom-in on the cylinder (I made the top and bottom slightly flat for initial contact). I might be doing the Interaction module settings wrong but I have no idea why it's behaving this way, so any help would be appreciated. Thanks in advance!

P.S. I only have the Elasticity values in the material properties, could that be an issue?

RE: Interaction module in ABAQUS

Hi crustaccione,

How are you simulating the compression of the cylinder and what material properties have you employed to describe the behaviour of the plates/cylinder?

Regards,
Dave
